NMEA 2000 Considerations

NOTICE

If you are connecting to an existing NMEA 2000® network, identify the NMEA 2000 power cable. Only one NMEA 2000 power cable is required for the NMEA 2000 network to operate properly.

A NMEA 2000 Power Isolator (010-11580-00) should be used in installations where the existing NMEA 2000 network manufacturer is unknown.

NOTICE

If you are installing a NMEA 2000 power cable, you must connect it to the boat ignition switch or through another in-line switch. NMEA 2000 devices will drain your battery if the NMEA 2000 power cable is connected to the battery directly.

You can connect your device to a NMEA 2000 network on your boat to share data from NMEA 2000 compatible devices such as a GPS antenna or a VHF radio. The necessary NMEA 2000 cables and connectors are sold separately.

This device is not powered through the NMEA 2000 network. You must connect the device to a power source (Connecting to Power).

If you are unfamiliar with NMEA 2000, you should read the Technical Reference for NMEA 2000 Products at garmin.com/manuals/nmea_2000.

The port labeled NMEA 2000 on the cradle is used to connect it to a standard NMEA 2000 network.
